86 Language - A pointer to a three character ISO 639-2 language identifier.\r
87 This is the language of the driver name that that the caller \r

93 specified by Language.\r

95 Returns:\r
96 EFI_SUCCESS - The Unicode string for the Driver specified by This\r
97 and the language specified by Language was returned \r

125 Routine Description:\r
126 Retrieves a Unicode string that is the user readable name of the controller\r
127 that is being managed by an EFI Driver.\r
128\r
129 Arguments:\r
130 This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.\r
131 ControllerHandle - The handle of a controller that the driver specified by \r
132 This is managing. This handle specifies the controller \r
133 whose name is to be returned.\r
134 ChildHandle - The handle of the child controller to retrieve the name \r
135 of. This is an optional parameter that may be NULL. It \r
136 will be NULL for device drivers. It will also be NULL \r
137 for a bus drivers that wish to retrieve the name of the \r
138 bus controller. It will not be NULL for a bus driver \r
139 that wishes to retrieve the name of a child controller.\r
140 Language - A pointer to a three character ISO 639-2 language \r
141 identifier. This is the language of the controller name \r
142 that that the caller is requesting, and it must match one\r
143 of the languages specified in SupportedLanguages. The \r
144 number of languages supported by a driver is up to the \r
145 driver writer.\r
146 ControllerName - A pointer to the Unicode string to return. This Unicode\r
147 string is the name of the controller specified by \r
148 ControllerHandle and ChildHandle in the language specified\r
149 by Language from the point of view of the driver specified\r
150 by This. \r
151\r
152 Returns:\r
153 EFI_SUCCESS - The Unicode string for the user readable name in the \r
154 language specified by Language for the driver \r
155 specified by This was returned in DriverName.\r
156 EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.\r
157 EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.\r
158 EFI_INVALID_PARAMETER - Language is NULL.\r
159 EFI_INVALID_PARAMETER - ControllerName is NULL.\r
160 EFI_UNSUPPORTED - The driver specified by This is not currently managing \r
161 the controller specified by ControllerHandle and \r
162 ChildHandle.\r
163 EFI_UNSUPPORTED - The driver specified by This does not support the \r
164 language specified by Language.\r
